Mars War

Mars War is a 32 level megawad for Doom II created by Nathan Lineback. It started off as an old WAD on The Library of Trantor BBS, which eventually stopped operating. This WAD was updated and completed after the author's multiple negative experiences with products.

The story starts off with the player, a lone Martian terraformer, lost in the middle of nowhere. The United Organizations of Earth have lead a terraforming project, and are threatening to take over the planet. Recent events have prompted an invasion from Earth, but something went wrong with their ships, which possess "space-warp" capabilities. Those ships were built by a company with the initials "MS".

The megawad is anti-Microsoft, the biggest clue to this being the final level, where the demonic visage of the final boss is replaced with an image of the face of as a. The starting room of the level is also in the shape of the Internet Explorer logo. The god mode face is replaced with that of, the mascot of the operating system.

The megawad was finished and released on the author's personal website in 1998. However, it was not on the idgames archive until 2003, when it was uploaded by Xaser.

Story
From the text file:

''The full story line is not important, but here it is anyway.

It is a thousand or so years in the future and you are a Martian terraformer stuck in a small station in the middle of nowhere.

Since the beginning of the terraforming project, the United Organizations of Earth have been threatening to take control. They do not like the independence that Mars has gained and view Mars as a threat.

The United Organizations of Earth are an accumulation of all governments, large corporations, and corporate owned governments of Earth. For over a hundred years they have tightly controlled the population of earth, at an almost microscopic level limiting what they are allowed to know and what they may do.

A few months ago, a huge number of radical, highly educated people escaped UOE persecution by coming to Mars in a large space-warp capable ship they built more or less by themselves without the knowledge of the UOE.

This was the last straw for the UOE. They attempted to quickly clone the space-warp technology and sent off an invasion force.

Only something went wrong with their new "space-warp" capable ships...''
